You are interviewing for a Data Engineer role where the discussion is expected to be highly technical and focused on how you execute real delivery work. You have been asked to lead a migration of a business-critical ingestion and transformation workflow from a legacy batch process into an orchestrated pipeline using OpenText Trading Grid integrations and OpenText Analytics reporting dependencies. The migration matters because downstream customer and finance reports are delayed daily, but the current process is poorly documented, one senior engineer knows most of the failure modes, and reporting stakeholders want no visible disruption during the transition.
How would you plan and execute this project, including how you would handle stakeholder alignment, technical risks, and delivery sequencing?
